The Dynamic Storage Technology (DST) quotas management system is a unified quotas management system that allows you to manage your disk space usage policy for DST shadow volume pairs. It is available in Novell Open Enterprise Server (OES) 11 SP2 and later. The ncpcon quotas command allows you to set directory quotas and user space quotas for the primary volume and secondary volume. The NSS file system independently enforces the quotas set on each volume.
